The conformation about the C=N bond is anti (1E); the C=N imine bond length is 1.287 (4) angstrom and the C=N-C angle is 122.5 (3)degrees. In the tetrahydrothienopyridine moiety, the six-membered ring has a flattened-boat conformation. In the crystal, molecules are stacked nearly parallel to (110) and a weak C-H center dot center dot center dot pi interaction is observed. The carbonyl O atom is disordered over two positions and was refined with a fixed occupancy ratio of 0.7:0.3.eninfo:eu-repo/semantics/openAccess[No Keyword]Editorial69O1116+WOS:0004216265001362-s2.0-848799892852404667310.1107/S1600536813016474Q3N/A
